The Blancos midfielder has spoken of the unity that he sees at the club and his strong rapport with the head coach, believing the side have the perfect recipe for cup success
The Germany international, who has scored five times in all competitions for los Merengues so far this campaign, expressed optimism for what his side can achieve this year in the wake of back-to-back wins over Barcelona.
"We are a team, and if you look at how successful we play, you cannot doubt that everything is alright within our squad," the 24-year-old told Welt am Sonntag.
"If we weren't a unit, we wouldn't be able to beat Barcelona. We treat each other respectfully; we're like a small family.
"I get along very well with Jose Mourinho. He supports me wherever he can and for me, he's one of the best coaches, if not the best coach in the world."
Madrid sealed victory in their Copa del Rey semi-final on Tuesday with a 3-1 win at Camp Nou before beating the Blaugrana once more on Saturday, this time 2-1 in La Liga, and Ozil suggested that the team are in a good position to build on that success.
"If you play for Real Madrid, winning titles is an obligation," the former Werder Bremen star continued.
"That's why we're looking forward to the Copa del Rey final and are determined to proceed to the next round in the Champions League as well.
"Our goal is to win both the Champions League and the Copa del Rey.
"Real Madrid against Bayern Munich would be a cool [Champions League] final, but there's still a long way to go."
Madrid currently sit third in La Liga with 55 points from 26 fixtures, still 13 points behind Barcelona, and travel to face Manchester United for the second leg of their Champions League last-16 tie on Tuesday.
